Description

Technical Field

[0001] The invention relates to a method for lifting a supporting tool for an auxiliary material vehicle and replacing running wheels of the auxiliary material vehicle. Background Art

[0002] In tobacco shred production lines, storage cabinets play a crucial role. As crucial process equipment, they store raw materials such as tobacco leaves, stems, and cut tobacco, playing an indispensable role in ensuring balanced production, moistening the tobacco leaves, and maintaining uniform moisture content. Currently, most common storage cabinets utilize a side-chain transmission structure. The entire cabinet consists of a spreading cart, a frame, a roller, a side-chain belt, a feed roller, a cleaning roller, and a transmission.

[0003] Among them, the paving vehicle, driven by a reducer, is on the track above the storage cabinet. With the support of the running wheels, it uses a step-by-step motion method to evenly distribute the materials delivered by the reciprocating material placing machine in the form of piles inside the storage cabinet, ensuring the proper storage of materials and the smooth progress of subsequent processes. However, since the paving vehicle needs to run back and forth on the track for a long time, its running wheels will inevitably face many problems. Long-term friction and mechanical movement make the running wheels very prone to wear, which not only affects the normal rolling of the running wheels, but may also lead to a decrease in operating accuracy; at the same time, the problem of running wheels moving also occurs from time to time, which will threaten the overall operating stability of the paving vehicle; in addition, the bearings, as key components of the running wheels, are also prone to damage under long-term load operation, further affecting the normal operation of the running wheels.

[0004] In view of the above-mentioned wheel failure, in order to ensure the normal operation of the paving vehicle and thus the stable operation of the entire storage tank system, the paving vehicle's wheels need to be regularly maintained and replaced. During maintenance and replacement operations, due to the special installation position of the wheels and their coordination with the track, the paving vehicle must be lifted up so that the wheels are higher than the storage tank track to ensure smooth maintenance.

[0005] The paving truck itself measures 13,800mm x 3,404mm, making it quite heavy. More critically, the paving truck was not designed with a dedicated jack for support. This means that during actual maintenance, workers can only use tools like crowbars to lift the paving truck before carrying out related maintenance work. This maintenance method has many drawbacks. First, the entire maintenance process requires the coordinated operation of multiple workers, which not only consumes a lot of manpower but also makes coordination between workers difficult, prone to operational incoordination, and thus affects maintenance efficiency. Second, the entire storage cabinet measures 27,803mm x 3,925mm x 4,058mm. During maintenance, workers are often working at height, and using crowbars to lift the paving truck presents significant safety risks. A slight mistake could lead to an accident, posing a serious threat to the safety of workers. Summary of the Invention

[0013] In the aforementioned auxiliary material vehicle top lifting and supporting tooling, preferably, both left and right ends of the installation box are open structures.

[0014] In the aforementioned auxiliary material vehicle lifting and supporting tooling, preferably, a handle is fixedly provided on the top of the connecting top plate.

[0015] In the aforementioned auxiliary material vehicle lifting and supporting tooling, preferably, the jack is placed on the jack mounting platform, and an arc-shaped pressing rod head is fixed to the top of the jack.

[0016] The method for replacing the traveling wheels of the auxiliary material cart using the aforementioned auxiliary material cart lifting support tooling comprises the following steps:

DETAILED DESCRIPTION

[0027] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] Embodiments of the present invention: Figure 1 and Figure 2 As shown, a supporting tool for lifting the auxiliary material vehicle includes a first support frame 16, a second support frame 17, a jack mounting platform 18 and a jack 19. The structures of the first support frame 16 and the second support frame 17 are exactly the same. Both have a fixed splint 1, a movable splint 2 and a mounting box 3. The top of the fixed splint 1 is fixedly provided with a connecting top plate 4. The top of the movable splint 2 is rotatably connected to the connecting top plate 4. The lower end of the movable splint 2 is connected to the lower end of the fixed splint 1 through a connecting piece. The mounting box 3 is connected to the fixed splint 1 through a transition bracket. One end of the jack mounting platform 18 is plugged and fixedly connected to the mounting box 3 on the first bracket 16, and the other end of the jack mounting platform 18 is plugged and fixedly connected to the mounting box 3 on the second bracket 17. A handle 15 is fixedly provided on the top of the connecting top plate 4.

[0029] When in use, the fixed splint 1 on the first support frame 16 and the second support frame 17 fits with the inner wall of the track, and the bottom surface of the connecting top plate 4 on the first support frame 16 and the second support frame 17 fits with the top surface of the track. The movable splint 2 on the first support frame 16 and the second support frame 17 is flipped over to fit it with the outer wall of the track, and then the movable splint 2 is connected to the fixed splint 1 using a connecting piece, so that the entire tool is fixed on the track. The transition bracket plays the role of avoiding the inner structure of the track. Then the jack 19 is placed on the jack mounting platform 18, and the jack 19 is used to lift the walking wheel to be replaced on the auxiliary material vehicle. Only one staff member is needed to complete the replacement of the walking wheel of the auxiliary material vehicle.

[0030] In this embodiment, the fixed splint 1, the movable splint 2, the transition bracket, the installation box 3 and the connecting top plate 4 are preferably made of 8mm thick high-quality steel plates. Of course, steel plates of other thicknesses can also be selected according to actual needs.

[0031] Specifically, since the structures of the first support frame 16 and the second support frame 17 are exactly the same, for the convenience of expression, the first support frame 16 is taken as an example for detailed description. The transition bracket includes a transverse transition plate 5 and a vertical transition plate 6. One end of the transverse transition plate 5 is fixedly connected to the fixed splint 1, and the other end of the transverse transition plate 5 is fixedly connected to the top of the vertical transition plate 6. One end of the mounting box 3 is fixedly connected to the lower end of the vertical transition plate 6.

[0032] The fixed plate 1 is arranged vertically, and the transverse transition plate 5 is perpendicular to the fixed plate 1. The transverse transition plate 5 is welded to the upper middle portion of the fixed plate 1. To enhance structural strength, the transverse transition plate 5 is connected to the fixed plate 1 via two second diagonal braces 8. The lower ends of the second diagonal braces 8 are welded to the end of the transverse transition plate 5 away from the fixed plate 1, and the other ends of the second diagonal braces 8 are welded to the top end of the fixed plate 1. The provision of the second diagonal braces 8 effectively prevents the transverse transition plate 5 from bending or deformation.

[0033] The fixed splint 1 and the movable splint 2 have the same size, and the height of both is greater than the height of the track. The width of the connecting top plate 4 is equal to the width of the track.

[0034] The top surface of the vertical transition plate 6 is welded to the end of the transverse transition plate 5 away from the fixed clamping plate 1. The vertical transition plate 6 is perpendicular to the transverse transition plate 5, that is, the vertical transition plate 6 is parallel to the fixed clamping plate 1. The transverse transition plate 5 serves to avoid other structures on the inner side of the track in the horizontal direction, such as the side beams of the storage cabinet. The vertical transition plate 6 is used to allow the jack 19 to be placed under the auxiliary material cart. Since the jack 19 has a certain height, if the vertical transition plate 6 is not provided, the distance between the installation box 3 and the bottom of the auxiliary material cart will be too small to place the jack 19.

[0035] The installation box 3 is arranged horizontally, with one side of the installation box 3 welded to the lower end of the vertical transition plate 6. The installation box 3 is perpendicular to the vertical transition plate 6. Similarly, to enhance the strength of the installation box 3, the installation box 3 is connected to the vertical transition plate 6 via two first diagonal braces 7. One end of each of the first diagonal braces 7 is welded to the end of the installation box 3 away from the vertical transition plate 6, while the other ends of each of the first diagonal braces 7 are welded to the upper end of the vertical transition plate 6. These two first diagonal braces 7 enhance the structural strength of the installation box 3.

[0036] The left and right ends of the mounting box 3 are both open structures. One end of the jack mounting platform 18 is plugged and connected to the mounting box 3 on the first support frame 16 and then welded and fixed, and the other end of the jack mounting platform 18 is plugged and connected to the mounting box 3 on the second support frame 17 and then welded and fixed.

[0037] Furthermore, the connecting top plate 4 is perpendicular to the fixed splint 1, and two first mounting tubes 9 are fixedly provided at one end of the connecting top plate 4 away from the fixed splint 1. A second mounting tube 10 is fixedly provided at the upper end of the movable splint 2. The second mounting tube 10 is located between the two first mounting tubes 9, and the second mounting tube 10 and the two first mounting tubes 9 are connected by a rotating shaft.

[0038] Two open slots 11 are provided at the lower end of the fixed splint 1, and the connecting parts include a threaded rod 12 and a locking nut 13. Two rotating shafts are provided at the lower end of the movable splint 2, and the threaded rods 12 are rotatably connected to the two rotating shafts. The positions of the two threaded rods 12 are opposite to the positions of the two open slots 11, and the two threaded rods 12 are respectively threadedly connected to the locking nuts 13.

[0039] In addition, in this embodiment, the jack 19 is placed on the jack mounting platform 18, and the top of the jack 19 is fixed with an arc-shaped pressure rod head 14. The provision of the arc-shaped pressure rod head 14 is of great significance. The arc-shaped pressure rod head 14 can better fit the auxiliary material cart roller and is used to position and lift the auxiliary material cart roller.

[0040] Compared with the traditional jacking rod head, the arc-shaped structure has the following advantages: 1. Increase the contact area and evenly distribute the lifting force: The arc-shaped structure can increase the contact area with the roller, so that the lifting force can be more evenly distributed on the surface of the roller. In this way, during the jacking process, damage to the roller due to excessive local force can be avoided, effectively protecting the structural integrity of the roller and extending its service life. 2. Improve positioning accuracy and enhance jacking stability. The arc-shaped jacking rod head 14 fits more closely with the roller and can play a better positioning role. During the jacking process, it can ensure that the position of the roller is relatively stable and will not deviate or shake, thereby improving the accuracy and safety of the entire jacking operation.

[0041] A method for replacing the traveling wheels of an auxiliary material vehicle using the aforementioned auxiliary material vehicle lifting and supporting tooling comprises the following steps:

[0042] Step 1: Flip the movable splints 2 on the first support frame 16 and the second support frame 17 to a horizontal state, then place the first support frame 16 and the second support frame 17 on the track from the inside of the track, so that the fixed splints 1 on the first support frame 16 and the second support frame 17 are in contact with the inner wall of the track, and the connecting top plate 4 is in contact with the top surface of the track, and then release the two movable splints 2;

[0043] Step 2: Adjust the positions of the first support frame 16 and the second support frame 17 so that the jack mounting platform 18 is located near the traveling wheel to be replaced on the auxiliary material vehicle;

[0044] Step 3, connect the two movable splints 2 to the two fixed splints 1 respectively through the connecting pieces thereon;

[0045] The specific operation method is to rotate the two threaded rods 12 on the movable splint 2 so that the two threaded rods 12 are respectively inserted into the two open slots 11 at the bottom of the fixed splint 1, and tighten the two locking nuts 13 to clamp the track between the fixed splint 1 and the movable splint 2;

[0046] Step 4: Place the jack 19 on the jack mounting platform 18 and use the jack 19 to support the rollers on the auxiliary material vehicle so that the traveling wheel to be replaced leaves the track;

[0047] Step 5: The staff removes the running wheel to be replaced and installs a new running wheel;

[0048] Step 6, controlling the jack 19 to retract so that the new running wheel contacts the track;

[0049] It also includes step 7, removing the jack 9 from the jack mounting platform 18, loosening all the locking nuts 13, separating the threaded rod 12 from the fixed splint 1, moving the first support frame 16 and the second support frame 17 to a position away from the auxiliary material vehicle, first flipping the two movable splints 2 to a horizontal state, and then removing the first support frame 16 and the second support frame 17 from the track.

[0050] The present invention enables one person to complete the replacement and maintenance of the auxiliary material vehicle's traveling wheels. In the prior art, replacing a traveling wheel requires five people working simultaneously for 2-3 hours. However, the auxiliary material vehicle lifting support tooling and replacement method of the present invention only requires one worker to complete the replacement in 40-60 minutes, greatly improving work efficiency.

[0051] When multiple people are operating, differences in their technical skills and operating habits can easily lead to problems with coordination, such as inconsistent force and uncoordinated movements. These problems can cause maintenance delays or errors. Single-person operation reduces the potential for problems caused by poor coordination, making maintenance work smoother and reducing the probability of operational errors.

[0052] The traditional maintenance method of using a crowbar to lift the paving vehicle poses a great safety hazard due to the large overall size of the storage cabinet and the high-altitude operation. The present invention uses tooling fixed on the track to provide stable and reliable support for the jack 19. At the same time, the arc-shaped top pressure rod head 14 can better position and lift the rollers, making the entire process smoother and safer. The one-person operation method also reduces the risk of personnel interfering with each other in complex high-altitude environments, effectively reducing the possibility of safety accidents. After adopting the solution of the present invention, the incidence of safety accidents has been significantly reduced, effectively ensuring the personal safety of operators.

[0053] By cooperating the fixed splint 1 and the movable splint 2 to clamp the track, and the good fit between the arc-shaped top pressure rod head 14 and the roller, the jacking process is made more stable. During the jacking process, the tooling can withstand greater pressure without deformation or displacement, and the arc-shaped top pressure rod head 14 can accurately transmit the jacking force to the roller, avoiding dangerous situations such as shaking or tilting of the paving vehicle due to unstable jacking, and further improving the safety of maintenance operations. The present invention uses the first support frame 16 and the second support frame 17 to jointly carry the jack mounting platform 18, so that the jack mounting platform 18 can withstand a larger load, has a longer service life, and has a wider range of applicability.

[0054] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
